Math Mammoth Measuring 2 is a worktext that covers time, temperature, length,
weight, and volume related lessons, aimed for 4th-5th grade. The focus in
these lessons is no longer on the actual act of measuring (as was the case
in earlier grades), but on calculations that
involve conversions between different measuring units.

The PDF version of this book is enabled for annotation. This means that if you prefer, the student can fill it in on the computer, using the typewriter and drawing tools in Adobe Reader version 9 or greater.

In the lessons about time, the students get to do fairly complex calculations concerning hours and minutes.
In lessons about temperature, the students are introduced to negative numbers and
even get to do a few simple calculations with them.

Each lesson about measuring units,
whether it is for length, volume, or weight, includes a table or a chart that lists the units and the
conversion factors. For metric units,
those tables always include all of the units, even when they are not in common
usage. For example, when studying metric units of volume, the chart looks like
this:

10
10
10

liter

L

for larger amounts of volume

deciliter

dl

(not used much)

centiliter

cl

(not used much)

milliliter

ml

for small amounts of volume

Only
milliliters and liters are dealt with in the lesson, but the chart shows the
two other units (deciliters and centiliters) as well, in order to familiarize students
with the two basic ideas of
metric measuring units:

The units
always differ by a factor of ten;

The units
are named consistently, with the same prefixes (milli-,
centi-, deci-, deca-, hecto-, and kilo-). These prefixes and their meanings are
not commonly studied in detail in fourth or fifth grade; instead they
are typically studied in 6th grade or later in conjunction with scientific
notation. You may at your discretion, explain them to the student even at an earlier time.

The last three lessons deal with using decimal numbers with measuring units, such as expressing
0.7 liters in milliliters, or converting 3.4 miles to miles and feet. These
lessons are better left for 5th grade. In these lessons, the symbol of a
calculator next to a problem ()
means that students are allowed to use a basic calculator to solve the problem.
